How do I change the UV bulbs in my transilluminator?
To save time and money, it is important to determine whether a bulb that does not light has burned out, or whether a ballast is defective. First, the filter frame and filter glass must be removed in order to access the UV bulbs. Next, the bulb that does not light should be exchanged with a good bulb from a properly functioning ballast (i.e. a ballast in which both bulbs light). If the bulb in question does not light, then a bulb replacement is in order. If the bulb does light, then a ballast needs to be replaced. Bulb Replacement Grasp the metal collar on each end of the bulb with the thumb and first finger. Gently rotate the bulb and pull it out of its socket. Do not force the bulb. Do not use excessive pressure and do not hold the bulb in the center. Replace the old bulb with the new one by following the instructions in reverse. Ballast Replacement To replace a defective ballast contact FOTODYNE for assistance by calling 800-362-3686.
